WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 325,529, dated September 1, 1885.

Application filed April 21', 1985.

To all whom it may concern:

Be it known that I, STEELE F. GILMORE, a citizen of the United States, residing at Princeton, in the county of Gibson and State of Indiana, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in window-screens, and is designed to produce an extensible screen that when not in use may be contained in a casing occupying but little space.

The improvement consists in the combination of a spring-roller containing a screen, a

casing nearly surrounding the same and having a top with a slot extending from one edge to the center, and a hook thereon retaining the extended end of the roller, and an extensible netting with a recessed strip on its free end, said recesses containing pins which engage over hooks on the window-case. The casing nearly surrounding the roller and being closed on top nearly completely prevents the entrance of dirt, while the slot and hook render the roller readily removable, and at the same time firmly hold it in place. The simple operation of lifting the strip easily disengages it from the hooks.

In describing the device reference is had to the annexed drawings, in which Figure 1 represents an elevation of a portion of a window with the screen attached; Fig. 2, a lateral section, and Fig. 3 a detail showing the top of the cylinder-casing.

The screen of netting A is secured at one end to a spring-containing roller, B, and at the other to a strip, G, which has slots or recesses D on the edge which bears against the casing when the net is secured in the extended posi- [No model.)

tion. These slots have each passed laterally across them a pin, E, which engages over a hook, F, on the casing, one hook for each pin.

On the strip 0 is a handle or ring, G.

The roller is journaled in a casing,H,which extends nearly around it, suflicient space only being left to remove the roller when desired. One edge of the casing has a bead, I, against which the net bears when extended. The top of the case is slotted at K from the center to the outer edge, said slot coinciding with the narrower diameter of the end of the rollershaft to prevent its turning. A hook, L, re-

tains it in place.

The operation is evident from the above description.

I am aware that heretofore spring-rollers partially incased have been used in connection with flexible window-screens, and also that pivoted hooks on slotted brackets have been used to retain the flattened end of the roller-shaft, and hence my invention does not broadly cover these features.

I claim A. window-screen consisting in the combination of a spring-roller, an extensible screen normally contained thereon, a casing nearly surrounding the roller, and a top or covering for the casing,having a narrow slot extending from the edge to the center to receive the flattened end of the roller spindle, and carrying a pivoted hook which normally retains the
